Many of our attitudes about food and eating are developed during childhood. Thus, the health and nutritional condition of the child, and of the subsequent adult, are shaped by childhood feeding experiences. However, our understanding of how food preferences, eating habits and skills are learned is still very rudimentary. We do know that human infants rely, to a much greater extent than perhaps any other mammal, on social means to acquire food-related information. The marmosets and tamarins are unique among non-human primates in the degree to which family members provision weaned young, much as we humans provision our young. This study proposes to use the golden lion tamarin as a model for the study of the development of food selection and eating habits in humans. It will focus on the interplay between independent trial and error learning and social learning about food during the tamarins' first year of life. Field observations and collection for nutritional analysis of food types given to immature tamarins by older group members will be used to examine the functions of provisioning, to describe the various means by which young acquire food and how these food acquisition strategies change during ontogeny, and to describe the roles of caretakers in determining food intake by the young. Behavioral experiments designed to measure the effects of food familiarity on food transfer interactions will be conducted on captive family groups to further examine the functions of provisioning. Playback experiments of infant begging calls also will be conducted on groups in captivity in order to more clearly assess the costs of begging for food by the young. Thus, natural variation in the behavior of wild animals and controlled experimental variation will be used to test hypotheses regarding the development of food selection and foraging skills.

我们对食物和饮食的许多态度都是在童年时期形成的。 因此，儿童以及随后成人的健康和营养状况是由童年喂养经历决定的。 然而，我们对食物偏好、饮食习惯和技能如何习得的理解仍然非常初级。 我们确实知道，人类婴儿比任何其他哺乳动物都更依赖社交手段来获取与食物相关的信息。 狨猴和狨猴在非人类灵长类动物中是独一无二的，因为它们的家庭成员提供断奶幼崽的程度，就像我们人类提供幼崽一样。 本研究拟使用金狮狨猴作为研究人类食物选择和饮食习惯发展的模型。 它将重点关注狨猴生命第一年期间独立试错学习和关于食物的社会学习之间的相互作用。 现场观察和收集老年群体成员给予未成熟狨猴的食物类型的营养分析将用于检查供给功能，描述幼猴获取食物的各种方式以及这些食物获取策略在个体发育过程中如何变化，并描述看护者在决定年轻人食物摄入量方面的作用。 旨在测量食物熟悉程度对食物转移相互作用的影响的行为实验将在圈养家庭群体中进行，以进一步检查供应的功能。还将在圈养群体中进行婴儿乞讨声音的回放实验，以便更清楚地评估幼崽乞讨食物的成本。 因此，野生动物行为的自然变异和受控实验变异将用于检验有关食物选择和觅食技能发展的假设。
